U-bolt assembly secures the cable assembly to the chute wall and permits chutes to link up

Working Load Limit is 1000 lb.

Breaking Strain is 10,000 lb. (Design Factor of 10:1)

Weight is 2 lb.

Notes

If your system will mix Superchute® sections with older and newer cable assemblies, install the sections with the older cable assemblies at the base of the system. This will put the stronger cable assemblies at the top of the system where they are most needed.

The Working Load Limit or WLL is the maximum load in pounds which should ever be applied to the component when the component is new or “in as new” condition and when the load is applied in direct tension to the component.

The Breaking Strain is the approximate load at which a new cable assembly will break when tested by applying direct tension to it at a uniform rate of speed in a testing machine. The breaking strain is obtained using a sample of cable assemblies.

The Design Factor is calculated by dividing the Breaking Strain by the Working Load Limit. It is also known as the Safety Factor.

Wire Rope vs Chain

Why doesn’t Superchute® use chain?
For general construction rigging never use a chain when it is possible to use wire rope. The failure of a single link chain can result in a serious accident but wire rope on the other hand is frequently composed of 114 wires all of which must fail before the rope breaks.
Wire rope gives you reserve strength and a chance to notice a hazard, chains do not.

From The Rigging Manual, CSAO, 1996.

Great strength & safety results from using wire rope composed of many grouped wires. In fact, there are 133 wires total!

Chains are built from single links. Each link has to support the entire load alone. If a link fails you will likely lose the whole chute system with potentially fatal consequences.

Keep corrosive substances away from the cable assemblies & do not weld near the chute system

Note:
The above strengths and specifications apply only to new, undamaged cable assemblies that were manufactured in February 1999 or later. See below for new height & weight limit information for chute sections with older cable assemblies. Some types of damage may not be visible to the eye. Abuse or wear and tear will reduce the strength of the cable assembly.
